These data
should be considered "provisional" until otherwise indicated.
The data are undergoing several rounds of QA/QC review
and some may be modified at a subsequent date. We chose to leave
the data hose on full blast whenever possible to familiarize ourselves
with the operation and maintenance requirements of the RUSS units
and to generate real data for use in developing curricula and lesson
plans. Data gaps were associated with various RUSS system upgrades
and occasional gremlins.NOTE: the fluorescence probe is set to report chlorophyll in units
of ug/L BUT these are relative values, only to be used to see how
fluoresence changes over time and depth. We will post acetone extracted
chlorophyll values as soon as they become available.
